Description of key information

The toxicity of the test substance on Scenedesmus subspicatus was evaluated in a static test over a period of 72 hours (Hüls AG 1993) acccording to EU method C.3. Five concentrations ranging from 28.0 to 253.0 mg/L (nominal) were tested. The stock solution (1 g/L) was stirred for 18 hours and filtrated. The ErC50 (72 h) was determined as >256 mg/L. 

Key value for chemical safety assessment

EC50 for freshwater algae:
256 mg/L
EC10 or NOEC for freshwater algae:
170 mg/L
